v 19 Claims. (Cl. 68-22) -The present invention relates to a device forprocess-- ing webs of textile fabric and other materials, according towhich processing operations known per se are carried out in a singleoperation while the material passes through the device in a continuousmanner.

Heretofore, the various operations for webs of textile fabric and othermaterials had to be carried out'on structurally different machines ordevices such as Foulards or padding machines, jigs, full width wettreating devices, impregnating devices, driers, and thermosettingdevices, or, if a processing by printing was involved, the operationshad to be carried out on different printing machines. These heretoforeknown devices have the drawback that one phase only, i.e. one type ofprocessing only, could be carried out on such machines. 7

Devices are known with which also different types of processingoperations, in other words multi-phase operations, can be carried outduring one passage of the respective material to be processed throughthe'machine. In such instances, however, pure aggregations are involvedof known individual devices for carrying out one-phase operations. Themere structural arrangement side by side of such one-phaseindividualdevices to form a larger machine for carrying out multi-phasemethods result in relatively huge devices.

the material and printing. These known devices, however, are notsuitable for'carrying out a plurality of fundamentally differentprocesses.

When carrying out processing or finishing operations in connection withwebs of various types, especially of A further drawback of these knowndevices consists in that they are suitable for one definite multi-phasemethod only, for instance for priming 7 United States Patent the mostcomplicated method combinations while requir textiles, yarn warps,fleeces of textile material and other A materials, papers, foils,'films, plastic and other mate-,

rial, it is of particular advantage to carry out the operational phasesin one operation and in as small a space as possible or to subdividesuch processes which heretofore were'carried out in one stage only intotwo or more stages,

and to carry out such operations in a continuous working operationwhereby the method will be greatly increased in efliciency. V

It is, therefore, an object of the present invention to provide amulti-purpose processing device of the general type mentioned abovewhich will overcome the drawbacks outlined above. I g

It is another object ofthis invention to provide a multipurposeprocessing device of the typeset forth in the preceding paragraph whichwill be suitable for carrying out completely different processingoperations which are independent of each other and can be carried outafter minor simple adjustments have been effected.

It is also an object of this invention to provide a device as set forthabove which will require a minimum of space.

These and other objects and advantages of the invention will appear moreclearly from the following specification in connection with theaccompanying drawings, in which:

General arrangement While heretofore the machines for carrying out so-'called one-phase operations, such as dyeing, permeating, printing,impregnating, and also machines for carrying out two-phase operations,such as adhesive impregnating, lining of at least two webs of textilesor priming, printing and dyeing, have been known, the machine accordingto the present invention allows the combination of the above.

mentioned one-phase operations with the likewise above mentionedtwo-phase and multi phase operations. Thus, by means of the machineaccording to the invention it is possible for instance to pre-dye andsubsequently during the same passage of the goods to print upon thegoods, in order to mention merely one of the numerous examples ofcombination. Thus, the machine according to the present invention makespossible the simplest as well as ing merely minor and quickly effectedadjustments of machine elements. In addition thereto, the machineaccording to the present invention also makes it possible to carry outcompletely new types of multi-phase operations which could not berealized on heretofore known machines, as for instance warp printing incombination with sizing, dyeing and printing and simultaneouslytherewith fixing ;the dye and the print.

The new multi-purpose machine for processing or fin;

ishing webs of textile fabrics, yarns, and other materials in which thematerials to be processed pass between roll" ers engaging each other andhaving containers associated therewith for receiving processingmaterial, is characterized in that the motor driven drive shaft hasassociated therewith Va tiltably journalled processing roller which isadapted to be subjected to various pressures, said processing rollerbeing exchangeable for at least another processing device or printingroller. For purposes of carrying out multi-purpose processingoperations, said drive shafthas associated therewith at'least oneworking group comprising a driven shaft and a squeeze roller carriedalong by the latter, and also a liquid container. The processing rollercooperating with the drive shaft is advantageouslyexchangeably'journalled on a tiltable lever which is adapted under adesired high pressure to. rest against the drive shaft. According to anadvantageous embodiment of the multi-purpose processing machine, twoworking groups (groups of rollers) are provided in the machine togetherWith the liquid containers associated therewith. The arrangement is suchthat one working group is located in the upper half of the machinewhereas the other working group is located in the lower portion rangedsymmetrically with regard to a central plane and when the rollers ofeach roller group are substantially identical to each other. In additionto the liquid containers mentioned above, advantageously the groups ofrollers may also be preceded or followed by so-called spreader arms orrods in such a way that the webs of materials are fed to each rollergroup in a certain predetermined direction. Furthermore, each rollergroup is preceded by a special roller on which the material to beprocessed or a back gray cloth is wound up. Between one of these rollersor docks and a group of rollers, there is provided in conformity with afurther feature of the present invention, a dust removing device whichmay be provided with a brush known per se and a suction device, theeffect of which may be improved by an electrifying apparatus. This dustremoving device has the purpose, prior to the first processingoperation, to remove any impurifications such as fibers or the like fromthe web to be processed. In addition to the so-called liquid containers,laterally sealed squeezing gaps are provided between said individualrollers where likewise a humidifying, wetting, coating, or otherchemical treatment of the goods maybe effected.

A further important feature of the multi-purpose processing machineaccording to the invention consists in the small space required by saidmachine. This advantageous feature is obtained primarily by journallingeach of the rollers on a shift lever, while two shift levers in the samedirection are actuated by a power accumulator only such as a pressurecylinder. In order to adapt the pressing pressure of thepower-interlocked rollers, the pressing rollers located in front whenconsidering the direction of movement of the material, have associatedtherewith a preferably manually operable adjusting device.

The processing roller associated with the drive shaft may, depending onthe particular processing operation to be carried out, have associatedtherewith a simple squeezing roller, a heated calender, a multi-dyeroller with solid dye. Furthermore, the processing roller journalled onthe tiltable lever operable by a power cylinder may be exchanged for arouleau or roller printing basket in which for instance two rouleauprinting cylinders are mounted with chassis and doctor blade as well asa pattern register adjusting device. The lower printing roller of thetwo printing rollers journalled in the rouleau printing basket hasassociated therewith a separate accumulator which presses these pressingor printing rollers against the drive shaft proper of the machine.

According to a further important feature of the invention, a motordriven trueing or dressing device is mounted on that tiltable lever armin which the various processing rollers may be journalled inexchangeable manner. This trueing or dressing device has associatedtherewith a drive motor which latter after tilting out the processingroller with tilting shaft, will drive on one hand the support of thetrueing device and on the other hand the color roller or printing rollerto be dressed. The dressing device permits a dressing or trueing of thecolor roller in order to eliminate unevenness which might form due touneven wear of the individual dye layers of the roller during theprinting operation.

The multi-purpose processing device according to the present inventionmay be operated in different manners by simple adjustment of individualparts thereof. As has been mentioned above, one-phase processingoperations, such as dyeing, permeating, printing, impregnating and thelike, may be carried out by said multi-purpose processing machine.Furthermore, webs of goods may be coated unilaterally or may be gluedtogether to another web ,of goods.

By means of the machine according to the present invention, whenproviding a roller printing basket on the shift lever carrying theprocessing rollers, deep printing or photogravure or copper plateprinting may be carried out. If the webs of goods to be printed upon aresubjected prior thereto to a dyeing operation, for instance a pigmentdyeing operation, the carrying out of multi-phase processing operationssuch as pigment dyeing, can be effected with subsequent roller print. Inaddition thereto, at least two webs of material may be laminatedtoether. When webs of material are to be provided with multi-colorprint, the webs of material may prior thereto be impregnated or treatedchemically. For instance a web of goods may first be provided in achassis with a primer and subsequently may be printed upon in multicolorprint. It is also possible that one and the same web of goods willduring a single passage through the machine successively be subjected todifferent one-phase operations. For instance, a web of goods to beprocessed may first be moistened, then be impregnated in a differentphase, and subsequently be provided with multi-color print. binedoperations on one and the same machine during one and the same passageof the goods to be processed cannot be carried out on any of theheretofore known devices of the type involved. The processing operationswhich will be set forth below are merely examples of an almost infinitenumber of other possibilities of application of the machine. Thesepossibilities from the simplest one-phase operation to the mostcomplicated combined operation may be varied merely by a slightadjustment in the machine.

Structural arrangement Referring now to the drawings in detail and FIG.1 thereof in particular, this figure shows a multi-purpose processingmachine designed as multi-color-printing machine of the so-called Devinaprinting machine type. As will be seen from FIG. I, mounted on theleft-hand side of the machine (with regard to FIG. 1) are two rollersW1, W2 having wound thereon the fabric material which is to be fedthrough the machine. The lower roller W1 contains the fabric material Stto be processed, whereas the upper roller W2 has wound thereon the backcloth M. Between the two rollers W1 and W2 there is arranged a device Efor withdrawing dust from the goods. When looking in the direction ofmovement of the goods, the material to be processed, for instance thematerial St to be printed upon, passes through the dust withdrawaldevice E via a roller or bar 2 to the lower three-roller-Foulard A1. Theintermediate roller 4 of the three rollers 50, 4, 6 is driven. The goodsare passed between the left-hand roller 50 and the intermediate roller 4and then move through a liquid container or trough 3. In the said liquidcontainer 3 the goods St are wetted by a liquid which may consist ofpure water or a chemical. The goods are passed over a deviating roller3a in the liquid container 3 and then pass over a spreader or roller 5.Finally, the goods are squeezed between the right-hand roller 6 and theintermediate roller 4. 'Aftr leaving the squeezer rollers, th goods passover a spreader or roller 7 and a deviating roller 8 to the drivingroller or cylinder 9, the so-called press cylinder and then around thedye cylinder 10.

In order to obtain a suificient contact of the webs of the goods St tobe processed with the dye roller 10, the roller 10 has associatedtherewith two further pressing rollers 11 and 12 for purposes ofincreasing the looping angle, each of said rollers 11 and 12 beingindividually pressed against roller 10 by separate pressing means, suchas the pressing cylinders 31, 32 and levers 11a, 12a. After the goodshave passed over the dye roller 10, which may also be called printingroller, the goods are approximately vertically conveyed in upwarddirection and are then passed through a drier not shown in the drawings.

The upper roller W2, as mentioned above, carries a follower material Mwhich is passed over a roller or bar 15 and from there moves between thesqueezer rollers 16 and17 into a trough 18. From here the material M ispassed over roller 19, between squeezer rollers 17 and 20 and overroller 21 to the press cylinder 9. The follower material M passes aroundthe rollers 9 and 10 in the same manner as the goods St, however onthe'back side thereof This possibility of carrying out so-called com-'sothat the follower material is printed upon only on the.

edges protruding beyond the goods St. The follower material M also takescare that the dye protruding beyond the printing Width on printingrollerwill be worn up to the same extent as that on the intermediate rollerportion which prints upon the goods St. Thefollower material M thenlikewise moves upwardly and, more specifically, is deviated toward theleft from printing roller 10 below the drier because the followermaterial does not have to be dried. After about 300 yards of the goodshave been printed upon, the dye roller is worn olf irregularly because,not all dye concentrations are uniformly conveyed to the goods. In orderto equalize the uneven Wear of the dye roller after a certain time ofoperation, the shift lever 22' has mounted thereon a trueing device Bwhich includes two supporting bars B1, B2 and a draw spindle Z whichmoves the support or carriageSu mounted on the supporting bars B1, B2toward the left and toward the right. Said support or carriage Su isshown in FIG. 2 and is driven by a motor I drivingly connected to twoshafts Ia, lb. Shaft Ia at the left side of motor I drives the drawspindle or feed spindle Z of the carriage Su of the honing device .13.The feed spindle Z is automatically turned off when the carriage Su hasreached its end position and has to be turned on anew while thedirection of rotation has to be reversed. Shaft Ib on the right-handside of motor I drives the printing roller 10 when the latter is tiltedoutwardly (see FIG. 3) and is to be trued.

FIG. 3 shows a cross section through the machine with the tilting frame22 in tilted-out position. This tilting is' effected by means of a powercylinder, preferablya compressed air cylinder 23. When frame 22 istilted inwardly, also motor I and trueing device B are tilted. In theoutermost tilted out position, motor I mounted on the' tilted frame 22is turned on through the intervention of switch SH shown inFIG. 2. MotorI is a threeephase. pole reversible motor and thus is adapted to rotateat obtained. By means of the knurled hand wheel 24 knife" 25 may bemoved against the printing roller 19. After the tiltable frame 22 hasbeen tilted through the intervention of a pneumatic cylinder 23, apreferably hydraulically effective brake 23' is required which isactuated in steps. In other words, when the piston of said hydraulicbrake cylinder 23' passe-s by certain bores in the wall of saidcylinder, the oil stream passing from the front to the back of thepiston is decreased or increased as to its cross section.

Inasmuch as when tilting out the tiltable lever 22, the pressure rollers11 and 12 must be tilted away from the printing roller 10, the tiltableframe 26 is turnable about pivot point 27 as will be evident fromFIG. 1. The tilting away of rollers 12 and 11 with lever 12a, 11a iseffected in conformity with FIG. 3 by means of a power operable piston,for instance a pneumatically operable cylinder 28 which is indicated bydash lines in FIG. 3. Piston rod 29 of cylinder 28 is connected to oneend of a lever 30 the other end of which is pivotally connected to thetiltable frame 26. When moving piston rod 29 outwardly, lever 30 isturned about shaft 27 and thus moves away parts 12, 12a, 11, 11a withcylinders 31, 32 by means of lever 26 connected to lever 30. The upperroller 11 and lower roller 12'are pressed against the printing roller 10by means of two preferably likewise pneumatically effective pressurecylinders 31 and 32, cylinder 31 acting upon the upper pressure roller11 and cylinder 32 acting upon the lower pressure roller 12. Therefore,when tiltable frame 22 is to be tilted outwardly for tr-ueing orchanging roller 10, frame 26 has to be lifted. To this end, first thetwo pressure rollers 11 and 12 are lifted off the printing roller 10. Assoon as this has been done, the cylinder 28 is subjected to compressedair so that the entire tiltable frame 26 tilts upwardly by an angle ofapproximately 90. When 6 the tiltable frame 26 is in its upper tiltedout position shown in FIG. 3, the two rollers are tilted into theirstretched position so that the goods St move upwardly and the followermaterial M can not be displaced from its substantially verticalwithdrawing direction.

The motor employed for driving the trueing' device B and forsimultaneously driving the dye roller 10 to be trued has a still afurther task. This additional task consists in driving the dye mechanismofthe rouleauprinting basket 33. The basket 33 according to FIG. 4.

has mounted thereon two copper intaglio printing rollers 34 and 35.These two rollers 34 and 35 have to be fed with dye. To this end, twodye feeding means are provided which pick up the dye from troughs 36 and37 and respectively convey the dye uniformly through brushes 38 and 35to a distributing roller 40 and 41 respectively which in their turnconvey the dye to the two intaglio printing rollers 34 and 35. Excessivedye is stripped ofi by means of a stripper, a so-called doctor blade,which is preferably made of brass sheet or of sheet metal andisresiliently arranged and variable as to its position and in particularwith regard to the pressure at which it may be pressed against therollers. The two doctor blades 42 and 43 are clearly shown in FIG. 4.The excessive dye is stripped off by the doctor blades from the rollers34 and 35 and returns to the troughs 36 and 37. The mounting of therouleau basket 33 in the tiltable frame 22 is effected in the tilted outcondition of the tiltable frame 22. Basket 33 is inserted into the samebearing means which support the printing roller 10. In this way, amongothers, a mutual pressure influence will be avoided when the twointaglio copper printing rollers are subjected to pressure. The copperroller 35 is thus subjected to pressure by means of cylinder the machineonly when the latter is employed for copper.

intaglio printing. When other working operations are to be carried out,cylinder 45 it to be removed. Cylinder 45 is connected to the supportingpipe of the tiltable frame 22 by means of vice 46.

Referring back to FIG. 1, two hand wheels H1 and H2 are I shown in sideview on the left-hand side of the two rollers W1 and W2. hand Wheels H1and H2. consists in lifting off the rollers and 15 fro-m the drivenFoulard rollers 4 and 17 or to reduce the pressure exerted thereupon.FIG. 5 shows a section through the lifting off device operable by saidhand wheels H1, H2. The said lifting off device comprises a spindle 51having a head 52 acting upon a packet of cup springs 53. Further-more, abolt 54 passes through spindle 51 at a point which is spaced from thehead 52. Spindle 51 is provided with a flattened portion 55 the purposeof which consists in preventing a turning of the spindle 51. Bolt 54 isarranged at a point which is determined by the effort not to overload 17and 4 respectively. This, however, has no influence upon the oppositelylocated rollers 20 and 6. This is due to the fact that the pressure atwhich the rollers 20 and 6 are pulled against rollers 17 and 4 dependson i the pressure prevailing in the two cylinders 57, 58 while thecylinders 57, 58 act upon lever arms 6a, 50a and Zita, 16a and turn thesame about shafts '6', 50' and 20', 16'. It may be added that the driveof the multi-purpose processing device is effected by a motor II (FIG.

2) which through a V-belt or the like acts upon a transmission III whichin its turn through the intervention a quickly disengageable clampingde-.

The purpose of these two.

of separate chain drives or the like conveys driving power to shaft 9aof drive shaft 9 and to shaft 4a of that roller of the working group A2which corresponds to the driven Foulard roller 4 of the working group A1and 17a. 7 FIGS. 6 to 14 diagrammatically show a number of possibleapplications of the machine according to the invention.

FIG. 6 shows the simplest method, namely the squeezing of wet goods orthe withdrawal of Water therefrom. The wet goods are passed from theroller W1 over a roller 2 between the squeezer rollers 4 and 5t andafter being squeezed pass around roller 4 between rollers 4 and 6 forfurther squeezing and from there over a deviating roller 66 into a drierT. The deviating roller 60 is arranged above the material directly infront of the inlet into the drier T.

FIG. 7 shows a method according to which the goods St are unilaterallycoated. The goods St pass from the roller W1 over a roller 7', theroller 8 to pressing cylinder 9 and are by means of roller 35unilaterally coated. The coat, for instance a dye or a cement or asynthetic material, is stored in trough 37 and is conveyed to roller 35by means of a distributing roller 39. In order to prevent the pressingcylinder 9 from being soiled laterally by the respective impregnatinglayer, it is advisable to pass a follower material M from roller W2 overdeviating roller 64 and roller 21 to the pressing cylinder 9. After thecoating has been effeotcd,.the follower material M is passed away fromthe goods St and over a deviating roller 65 below the drier T toward theleft where it is again wound up. The goods St are conveyed over roller65 to the dried T.

FIG. 8 diagrammatically illustrates how the copper intaglio printingmethod may be carried out on the machine according to the invention. Thegoods are passed from the roller W1 over roller 7 to roller 8 and fromthere to the pressing cylinder 9. Below the goods there is again afollower material M which is withdrawn from roller W2 via deviatingroller 64 and roller 21 and passes to the pressing cylinder 9. The websare printed upon in conformity with the description of FIG. 4 by copperintaglio printing rollers 34 and 35 which are fed by dye .applicators 38and 39 with dye from the troughs or reservoirs 36, 37. The goods leavethe machine in upward direction and are deviated by rollers 65 and 65'.The printed goods St pass through the drier T whereas the followermaterial is passed toward the left below the drier.

FIG. 9 shows the pigment coloring by rouleau printing. To this end, thegoods St are passed from roller W1 via roller 2 to the squeezer bite 67where they are chemically pre-treated and passed through the two rollers50 and 4 into the trough 3 where the goods are pigment dyed. The thusdyed goods are passed via roller 5 between the two rollers 4 and 6 andover roller 3 to the printing cylinder 9 where the goods are printedupon by the two copper intaglio printing rollers 34 and 35. Also in thisinstance, the follower material M passes below the goods after beingwithdrawn from roller W2 and guided over the deviating roller 64 androller 21 and between goods St and drive roller. After the printing hasbeen effected, the follower material M is passed upwardly by means ofrollers 34 and 35 over deviating roller 65 and conveyed toward the leftwhereas the goods move over the deviating roller 65' into the drier T.

The arrangement is also suitable for unilateral pigment dyeing, if adoctor blade is mounted above roller 6, and the goods St are guidedaccordingly.

FIG. illustrate the laminating of two webs of goods. The webs of goodsSt are passed from roller W1 over the deviating roller 66 to roller 5into the bite between rollers 4 and 6 and then over the deviating roller7 and roller 8 to the roller 9. The webs of goods St are withdrawn fromroller W2 and passed over the deviating roller 64 to roller 21 and thenlikewise to the roller 9.

The binder, for instance rubber, employed for lining is located in thebite 67. By means of the relief device according to FIG. 5, roller 54)is withdrawn from roller 4 to a certain extent. This extent determinesthe thickness of the rubber coating. Roller 4 driven by a motor nowdraws a rubber layer into the bite between the rollers 4 and 6 and coatsthe upper side of the goods St. This upuper side will during themovement around the pressing cylinder 9 contact the goods S2. For makingthe intermediate layer permanent, a roller 63 is provided which ismounted on the tiltable frame 22 and may be heated. The two webs ofgoods St and St are connected to each other by pressure and thetemperature between the rollers 9, 68, and via the deviating roller 65'leave the machine. If it should be necessary, they may be passed throughdrier T for hardening the binder.

Above roller 6 there may be provided a doctor blade (not shown in thedrawings). Such doctor blade will be indispensable when the laminatingor lining mass is being deposited on one side only, namely the innerside of the web St. In such an instance, the outer sides of the two websSt and St remain without laminating or coating mass.

FIG. 11 shows the lining of three webs of goods. The webs of goods Stpass from roller W1 via rollers 7 and 8 to the pressing cylinder 9. Thewebs of goods St pass from roller W2 to roller and from there betweenrollers 16 and 17, through trough 18 and from there over roller 19,roller 20, deviating roller 64' and roller 21 likewise to the pressingcylinder 9. The web of goods St will be coated on both sides during thepassage thereof through trough 18. The trough 18 contains the coatingmaterial in liquid form. The web of goods St" passes from roller W3 overdeviating roller 64 to roller 21 and from there directly to the pressingcylinder 9. By pressing against the heated calender 68 which may bepressed against the pressing cylinder 9 by means of the tiltable frame22, the said three webs of goods are connected to each other and whilemoving vertically upwardly pass over the deviating roller 65' and areconveyed through the drier T which, if necessary, will harden thebinder.

FIG. 12 illustrates the multi-color printing according to the so-calledDevina method. The goods are withdrawn from roller W1 and passed overthe dust withdrawing device E, roller 2, then between rollers 4 and intothe trough 3 and from there over roller 5 between rollers 4 and 6, overdeviating roller 7 and roller 8 to the pressing cylinder 9 where thegoods are printed upon by the printing roller 10. The goods are loopedaround the printing roller 10 and are pressed thereagainst by an upperroller 11 and a lower roller 12. The goods then leave the machine viadeviating roller and are dried in the drier T. In order to preventsoiling of the pressing cylinder 9, a follower material or back cloth ispassed between pressing cylinder 9 and the goods to be printed upon.This back cloth is withdrawn from roller W2 and passed over. roller 15,between rollers 17 and 16 into the trough 18 and over roller 19 and thensqueezed between rollers 17 and 2t). The trough 18 contains wettingliquid. The back cloth M is introduced between the pressing cylinder 9and the goods St to be printed upon. The designation Devina relates tothe printing method by means of a mosaic roller 10 on which the dyes aredeposited in form of consistent masses.

If a simultaneous priming or bottom dyeing of the goods St to be printedupon is desired, the method according to the present invention will becarried out in conformity with FIG. 13. As will be evident from FIG. 13,the goods are withdrawn from roller W1, passed over dust withdrawingmeans E, roller 2 and are further passed between rollers 50 and 4.. Thesqueezing gap or bite is filled with wetting liquid while known lateralseals fitted to the rollers at the end of the gap will assure that thewetting liquid will not flow oif laterally from the rollers 54 4. Afterthe goods St have passed the squeezing gaps 67 they pass through trough3 where they are dyed and then pass over roller 5 and between therollers 4 and 6 and leave the working group A1,-while the goods St arestripped of excessive dye. The goods then pass via deviating roller 7 toroller 8 and to the pressing cylinder 9; the path of the back cloth Mcorresponds to that of FIG. 12. Also in this instance, a multi-colorroller It) coated with dye material rests against the pressing cylinder9, said multi-color roller being pressed against the pressing cylinder 9by upper and lower rollers 11 and 12. After the goods have been printedupon, they leave the machine via roller 65' and move into the drier Twhereas the back cloth leaves the machine via roller 65.

It is, of course, .to be understood that a dyeing may also be effectedwith the bite of rollers 4 and 6 of FIG. 12. In this instance, a doctorblade is to be arranged above roller 6, and the web is to be guidedaccordingly. It is also possible by means of the doctor bladeunilaterally on that side of the web which is not to be printed upon, todeposit a mass such as which will prevent the Davina print from passingthrough the web, thereby keeping the non-printed-upon side of the webclean and without designs.

' FIG. 14 illustrates a method according to which the webs of the goodsSt are not only processed in the working group All 'but alsoadditionally in the working group A2. The goods St are in addition tobeing subjected to a wetting operation also subjected to a dyeingoperation. If two further treatments of the goods are required, thegoods are passed over the dust withdrawing device E, the deviatingroller 2', roller 2 and then passed to the. squeezing gap 67 in front ofthe rollers 16, 17 which squeezing gap 67 is filled with wetting liquid.This wetting liquid simultaneously serves for wetting the followermaterial M withdrawn from roller W2. The goods leave the squeezing gapbetween rollers 16 and 17 and move vertically downwardly via roller 2into the squeezing gap 67 between the rollers 50 and 4. In thissqueezing gap 67, the goods are subjected to a further chemicaltreatment, such as a dyeing operation. This chemical treatment may alsobe an impregnating operation or any other chemical operation as they arecustomary nowadays with synthetic materials. After the goods have leftthe squeezing gap between rollers 59 and 4, the goods enter the trough 3where they are treateda third time. The

goods are passed via holders or rollers 5, 6, 7, 8 to the pressingcylinder 9 and to the printing roller pressed thereagainst. Pressurerollers 11, 12 press against the printing roller 10. After the goodshave been subjected to the multi-color printing operation, they arewithdrawn in customary manner, whereas the follower material M, thepurpose ofwhich consists in protecting the pressure cylinder 9 againstsoiling, will in a manner known per so be passed over the deviatingroller 65 below the drier.

FIG. illustrates a further processing, namely a twophase dyeingmethod,such as the naphthol dyeing. With this dyeing method, the goodswithdrawn fromrollerWl will be primed or impregnated in the workinggroup A2 and will be naphtholated in working group A1; In order to beable to increase the speed of passage of the goods also when heavy goodsare involved and in order to assure a uniform dying effect, the primingoperation is carried out twice in the working group A2, namely in thelaterally sealed squeezing gap 67' and also in trough 1%.

The squeezing in squeezing gap 67 immediately following the priming willassure a good venting of the goods. After squeezing the goods once morebetween the .rollers'17 and 18, the goods are passed .over the deviatingroller and the roller 2 into the squeezing gaps 67 where the goods arenaphtholated or coupled for the first time. Following the squeezingoperation between rollers 50 and 4, thegoods are naphtholated a secondtime in trough 3 and are subsequently squeezed again between rollers 4and 6. The goods are then passed over the rollers 7, 8 and 65' into thedrier T. Advantageously, the rollers 11 and 12 are coated with anelastic material, for in stance elastic-rubber or Mipolan.

In the drawing, the webs of goods are indicated by dot-dash lines,whereas the follower material which is not printed upon and is employedmerely for protecting the pressure cylinder, is indicated by twodot-dash lines.

In order to permit the changing ofthe machine from one phase to anotheroperational phase and to simplify such change, the lateral walls of themachine are provided with bores for mounting the various rollers anddeviating rollers which according to the invention may be mounted indifferent positions so that the respective rollers can without dimcultybe moved to their predetermined position.

With regard to the arrangement shown in FIG. 16, it will be noted thatthe spindle Z has mounted thereon a nut 66 fixedly connected to thesupport Su. Rotation of spindle Z in clockwise direction causes the nut66 to move in the direction of the arrow 67, whereas rotation of spindleZ in counter-clockwise direction will cause nut 66 to move in thedirection of the arrow 68'.

The alternate rotative movement is produced by a control transmissionthrough the intervention of two oppositely toothed ratchet wheels 69 and70. Mounted on shaft Ia is a crank.71 which, by means of a connectingrod 72 is adapted to allow a tiltable yoke 74to ,oscil-, late about ashaft 73. The ends of the two yoke halves 75, 76 have mounted thereontwo rollers 77, 78 which resiliently rest against the two pawls 79, 80.The resiliency is made possible by a torsion spring 81 built into shaft73. a i When occupying its ordinary position, shaft 73 is held in itsintermediate position by a torsion spring 82 which is likewise builtinto shaft 73. In this way, pawl 79 cannot engage the ratchet 69, norcan pawl $0 engage the ratchet wheel 70. If, by means of lever 83, shaft73 is tilted in the direction indicated by the arrow 34, the yoke 74-and roller 77 will bring pawl 79 into engagement with ratchet wheel 69.The spindle Z will then movein clockwise direction, while nut 66 willmove in the direction of the arrow 67. In order to bring about saidengagement, lever 86 is displaced axially, after said tilting movement,in the direction of the arrow $5 so that it will also displace shaft 73axially. Lever 86 at this time engages key 87 by the groove 88 in thehub of the lever which will hold the lever in its tilted position.

In this position, nut 66 will move in the direction of the arrow 67until support Su abuts the hub of lever 83, and moves the same towardthe left in the direction of the arrow 89 until the key 87 leaves groove88 and the torsion spring 82 returns shaft 73 to its intermediateposition. As mentioned in the intermediate position of shaft 73, neitherof the pawls 79, 8t) engages the respective ratchet 69, 70. Spindle Zwill now be at a standstill and consequently, also support Su.

If the opposite movement a nut 66 is to be initiated, lever 83 or lever86, depending on whether the operator is located toward the right end ortoward the left end of the machine, will be tilted'in the direction ofarrow 99 whereby roller 73 presses against the pawl to cause pawl 80 toengage ratchet 70, and whereupon spindle Z will begin to rotate incounter-clockwise direction. 1

, In view of this rotation, nut 66 moves in the direction of the arrow68. In order to lock shaft 73 in the last mentioned position, key 91 ismounted on the left-hand side of the machine and which key engages agroove 92 in the hub of lever 83. To efifect this engagement, shaft 73is displaced axially in the direction of the arrow 89 toward the leftwith regard to the drawing. When support Su reaches its right-hand endposition, it abuts the hub of lever 86 and displaces the shaft in thedirection of the arrow until the key 91 has left groove -92. Due to thetorsion spring 82, shaft 73 will be tilted to its center position sothat the support will again come to astop.

It is, of course, to be understood that the present .in-

ii a
